+Subject: Revert "driver core: enforce device_lock for driver_match_device()"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit adc1796eced46b48e23ec200a219d635f33a38ee which is
+commit dc23806a7c47ec5f1293aba407fb69519f976ee0 upstream.
+
+It causes boot regressions on some systems as all of the "fixes" for
+drivers are not properly backported yet.  Once that is completed, only
+then can this be applied, if really necessary given the potential for
+explosions, perhaps we might want to wait a few -rc releases first...
